Rhythm and blues singer drummer, broadcaster, and club-owner Ernest Kador, Jr., known by the stage name Ernie K-Doe, was born in New Orleans on February 22, 1933. He was best known for his 1961 hit single “Mother-in-Law”, which was written by Allen Toussaint, and went to number 1 on the Billboard pop chart..His song "Te-Ta-Te-Ta-Ta" reached number 21 the same year, and "Later for Tomorrow" reached number 37 in 1967, but he never had another top 40 pop hit.

In the 1980s K-Doe did radio shows on New Orleans community stations, occasionally causing problems for the noncommercial stations with his frequent self-promotion.  In the 1990s K-Doe began to call himself "The Emperor of the Universe" and wore a cape and crown, becoming a famous local eccentric in New Orleans. Always an elaborate showman, one of K-Doe's most notable later performances ended with him performing seven continuous renditions of "Mother In Law" while dancing in front of the Aquarium of the Americas’ shark tank dressed in a green plumed cape. "Here Come the Girls", written by Allen Toussaint and recorded by K-Doe, was released in 1970, but was not a hit until it was used in an advertising campaign in 2007 and re-released. In 2008, a cover by the Sugarbabes reached number 3 on the UK charts, and in 2017 it was covered by Trombone Shorty. In 1994 The Mother-in-Law Lounge was opened by Ernie K-Doe, and it became an icon in the local community. K-Doe continued performing and occasionally recording until shortly before his death on July 5, 2001.
